What is this?
The human skull is like a strong, bony helmet that protects your super-important brain. The 'cranial floor openings' are all the special holes found on the inside bottom of this helmet. These holes are like tiny doorways that let nerves and blood vessels travel in and out, connecting your brain to everything else.
